How drag and drop a node in a TreeView ?
Hi,
I want drag and drop a node in a treeview but i don't know how to get this result. I can drag a page item in a treeview or drag a node in a page item but not a node in another.
Can you help me ?
Regards,
Damien Fontaine
Your implementation of DoAddDragContent() is a little thin looking.
If you look at the example in the SDK (BscDNDCustomDragSource.cpp) you might need to add at least:
// we get the data object that represents the drag
InterfacePtr<IPMDataObject> item(DNDController->AddDragItem(1));
// no flavor flags
PMFlavorFlags flavorFlags = 0;
// we set the type (flavour) in the drag object
item->PromiseFlavor(customFlavor, flavorFlags);
Also, check that DoAddDragContent() is actually being called.

How to drag and drop tab nodes between tab panes
I'm working on example from this tutorial( Drag-and-Drop Feature in JavaFX Applications | JavaFX 2 Tutorials and Documentation ). Based on the tutorial I want to drag tabs between two tabs. So far I managed to create this code but I need some help in order to finish the code.
Source
tabPane = new TabPane();
Tab tabA = new Tab();
Label tabALabel = new Label("Main Component");
tabPane.setOnDragDetected(new EventHandler<MouseEvent>()
@Override
public void handle(MouseEvent event)
/* drag was detected, start drag-and-drop gesture*/
System.out.println("onDragDetected");
/* allow any transfer mode */
Dragboard db = tabPane.startDragAndDrop(TransferMode.ANY);
/* put a string on dragboard */
ClipboardContent content = new ClipboardContent();
content.put(DataFormat.PLAIN_TEXT, tabPane);
db.setContent(content);
event.consume();
What is the proper way to insert the content of the tab as object? Into the tutorial simple text is transferred. How I must modify this line content.put(DataFormat.PLAIN_TEXT, tabPane);?
And what is the proper way to insert the tab after I drag the tab:
Destination
tabPane.setOnDragDropped(new EventHandler<DragEvent>()
@Override
public void handle(DragEvent event)
/* data dropped */
/* if there is a string data on dragboard, read it and use it */
Dragboard db = event.getDragboard();
boolean success = false;
if (db.hasString())
//tabPane.setText(db.getString());
Tab tabC = new Tab();
tabPane.getTabs().add(tabC);
success = true;
/* let the source know whether the string was successfully
* transferred and used */
event.setDropCompleted(success);
event.consume();
I suppose that this transfer can be accomplished?
Ref javafx 2 - How to drag and drop tab nodes between tab panes - Stack OverflowI would use a graphic (instead of text) for the Tabs and call setOnDragDetected on that graphic. That way you know which tab is being dragged. There's no nice way to put the Tab itself into the dragboard as it's not serializable (see https://javafx-jira.kenai.com/browse/RT-29082), so you probably just want to store the tab currently being dragged in a property.
Here's a quick example; it just adds the tab to the end of the current tabs in the dropped pane. If you wanted to insert it into the nearest location to the actual drop you could probably iterate through the tabs and figure the coordinates of each tab's graphic, or something.

JTree Drag and Drop (Multi Nodes)
Hi All!
I have been searching the forums for a few hours over the last few days and have found some nice examples and explanations on how to implement drag and drop for a jtree.
However, I would love to know how this is accomplished when selecting multiple nodes.
I want to be able to see all the selected nodes being dragged...
Anyone implemented anything of the sort... or even just knows how to do this?
Thanks in advance!!
Aaron.When you drag get the [x,y] mouse position and use the JTree method:
getRowForLocation(x, y) for node you at the also for the parent node location of the child node.
Once the childY is less than childParentY, you stop the drag.
Hope that helps? -
Drag and Drop different nodes within a JTree
I have a JTree that represents a hierarchical object. Within the tree are different nodes representing different objects, each within a container,
For Example:
A
-B container
-- B NodeObject
-- B NodeObject
-C Container
-- C NodeObject
-- C NodeObject
I have got the drag and drop working but as the gesture listener is on the actual JTree object it allows me to drag any object to any other place.
What i want to be able to do is to force the drag and drop to allow only objects of type C to be put in the C container, etc and to reject any moves
over other containers.
As TreeNodes are not Components how do i force this behaviour?
If i have to i can force the behaviour after the mouse has been released but I would prefer it if Swing would show the correct mouse over icons
when I put an object over the wrong container.
Thanks

I would like to archive hundreds of my emails that currently exist in my apple mail email filing system by moving them into file folders in the finder. I can do this easily with a single email but it wont let me do it with multiple emails or a complete folder. Is there any way of do this easily?
Thanks very much for this. However, I understand how dragging and dropping files normally works. It just seems the it wont work when you do it with emails when you are transfering them into a normal finder system folder. If you highlight one file and drag it to a finder folder it works, but when you drag multiple, it just wont let you do it.
Is there any work around for this? Thank you once again for your time. -
Is there a way to drap and drop JTree nodes without resorting to hacks? http://www.javaworld.com/javatips/jw-javatip97.html outlines a hack to get drag and drop working but it is kinda old. I am wondering whether there is a now a way to do this in Swing. http://weblogs.java.net/blog/shan_man/archive/2006/01/first_class_dra.html outlines a seemingly promising way but when I tried it it still wouldn't let me drag JTree nodes. (btw, if you are going to try it, you must replace TransferHandler.TransferInfo with TransferHandler.TransferSupport. It has apprently been renamed.)
I have implemented drag and drop of nodes in JTree they same way it is explained in JavaWorld link that you mentioned, I customized it for my application and it worked great.

I'm using the Flex DragManager in an AdvancedDataGrid with
HierarchicalData to allow the user to drag and drop tree nodes to
re-order them. It is working fine. The problem I am having is with
the drag image. The drag image does not always show up. It seems
like it will appear for one drag and drop. Then if I try to drag
another tree node I do not get the drag image there is just a line
to show I'm dragging something.
When I say drag image I mean the faded image of the text of
the tree node which appears as I drag the tree node.
I am using the following properties on the AdvancedDataGrid
to enable drag and drop:
dragEnabled="true" dropEnabled="true" dragMoveEnabled="true"
Now if set dragMoveEnabled="false" then I do get a drag image
everytime. But I need move the tree nodes around not copy them so I
need dragMoveEnabled="true".

I am new to Oracle but not to VS. I have downloaded and installed the newest tools for Developer, having first tried the install for VS2003.net (which refused to install on my VS 2005.) I got the beta download and installed it, but my oracle explorer shows nothing. Any attempt to add a connection results in an error ORA-12560:TNS:protocol adaptor error. I had the full install of 10g r2 on my notebook, but removed it and opted for the XE version. I removed the Oracle_Home environment variable prior to installing XE. I am trying to connect to the HR database, and the account is unlocked. I saw a reference to the tnsfiles file, and that seems to be the problem, but I don't know what to do about it. Thanks in advance to anyone who can offer help.

Drag and Drop between JTree and Labels in 2 different panes
Hi,
I am using JDK 1.4.1 and am trying to implement Drag n Drop between a JTree and JLabels with ImageIcons, both on different panes.
I got the DnD working fine on the tree. but i cant get to drag and drop the label from the other pane, on the Jtree as a node. I am getting confused with the DataFlavors, and also wonder if there is something else that i have to do for DnD between 2 panes. Can someone give me any leads on this, please? The Panes I am talking about are splitpanes.
thanks,
Sri.hey thanks Dennis!! I was hoping you would respond to my question, as I have seen a lot of your replies. yes, the example you gave would be helpful. but i am trying to implement this in 1.4.1, with the new drag and drop in swing. and i am getting confused wiht theh data flavors etc.
my problem at hand is :
I have a tree on the left pane. i can drag and drop the nodes on the tree itself. (i already did that...no problem). I have Jlabels with imageicons (actually wrapper classes with labels and imageicons) on the right pane. i have to be able to drag these labels to the tree such that they form a node.
I have one class the NodeSelection class which extends TransferHandler and implements Transferable. i was able to do DnD for the tree using this. I customized the importData method in this.I thought that i can just use the same class to create the transferhandler and transferable, and just use a different implementation for the importData method if the data being dragged is from the label.
well, my thoughts and ideas were ok...but i can implement it...so they must be wrong ;-)
Can u please suggest another way to do this. I have a deadline to meet and am stuck here :-( any suggestions or tips or hints would be very helpful and appreciated!!
Thanks,

Prevent drag and drop for QT web movies
I've tried protecting QT movies on my web site using kioskmode, like this:
http://www.apple.com/quicktime/tutorials/embed2.html#kioskmode
but despite what Apple says, drag and drop remains enabled. Anyone know how to fix that?
conranIf your goal is to "protect" your videos the kioskmode="true" tag will be the weakest link.
http://streamingmediaworld.com/gen/voices/praja/praja1.mov
You can open and save the file using the Safari (or any other browser) by using the Safari Activity window.
You can also download by dragging the link to the Download window.
I use the Save As Un-Editalbe droplet on some of my files. Needs some work to run on a Tiger OS and you can email me for a copy that is Tiger "ready". Screen name (left) @ mac.com.
But I still don't understand how drag and drop works if the file is "protected" via kioskmode="false" tags. -
Dragging ande dropping into a frame?
Hi all,
I am new to Swing Programming and i have a problem in implementing the JTree.
According my requirement i need to drag a child node of the Jtree and drop into a frame which is adjacent to the JTree pane.
But i am struck at only dragging and dropping the child node inside the tree itself,
Please help me by some links or tutorials or any help is greatly appreciated.
Thanks In advance.....
Looking forward for your reply.....
Thanks again,
karthik.now i can able to compile the source code.thanks for that but my actual problem is i am creating a GUI. i am using splitpane to split my Frame. and my left split pane contains the XML schema in the form of a JTree. and i need to drag and drop the nodes of a JTree on to right split pane which sub divided in to some regions. i can able to open the xml file in to left split pane as a Jtree. but unable to drag and drop the Nodes in to rightsplit pane.

How to get UIComponent of the selected node in af:tree with drag and drop
Hi
Are there examples showing how one could get a UIComponent using DropEvent to be used with a Popup showing as a custom "context menu" at the target node ?
Right now, with dropEvent.getDropComponent, we could only get the tree.
We like to get its selected node so that the popup shows at the node level, not at the tree level.
ThanksHi Frank
Thanks for responding.
We like to show on our custom "context menu" using PopupHints (not using facet name contextmenu) with 3 commandMenuItems.
Since component id is needed by PopupHints to place this custom "context menu", we tried
RichTree dropTree = (RichTree)dropEvent.getDropComponent();
alignId = dropTree.getClientId(context);
// alignId = pt1:pt_region1:1:pt1:pc1:navTree
getClientId returns us the tree id and hence the context menu is placed next to tree.
We like to place the context menu next to a target node of the tree when dragging and dropping.
But we couldn't figure out how to get that node id.
In your suggestion,
List dropRowKey = (List) dropEvent.getDropSite();
RichTree dropComponent = (RichTree) dropEvent.getDropComponent();
dropCompoent.setRowKey(dropRowKey);
how do we then get the id of this node then ? What's the method ?
Thanks Frank -

Thank you.Hello, if you had this message you had created BP....
Now you don't have to user USERS_GEN this transaction is used only in first action, when you create the user in R/3 and then you pass this user to EBP in the organizational structure.
Now you have to:
1) Go to PPOMA_BBP
2) Double click on organizational unit that you want to put this user (purchasing organization or purchasing group box for example)
3) Select assign button in the top of the functions in the transaction
4) Click on incorporates -- position
